Abstract

The invention discloses a micro-CT-based rice tillering characteristic nondestructive measurement device and a measurement method thereof. The device comprises a lifting platform, a translation platform, an object carrying rotating platform and the like; the method comprises the steps of using a mechanical arm to carry a detected sample onto the object carrying rotating platform, and the like. According to the device and the method, provided by the invention, the mechanical arm is used for completing the carrying operation, focal plane array images of the detected sample can be collected through a micro focal spot radiation source, the object carrying rotating platform and a flat panel detector, then a tomographic reconstruction image of the detected sample can be realized on the basis of a computer system, and the tillering characteristics including tiller number, stem diameter, stem wall thickness, area of marrow cavity, total area, tillering angle and the like of rice tillering can be obtained at the same time through a machine vision technology.

Description

technical field [0001] The invention relates to the technical field of machine vision detection, in particular to a micro-CT-based non-destructive measurement device for tillering traits of rice and a measurement method thereof. Background technique [0002] Since rice lodging resistance is the key problem restricting rice yield increase, and with the rapid development of rice functional genome and molecular breeding, it is necessary to identify phenotypic traits under different growth conditions such as biological stress or soil nutrients, and use the method of systematic analysis Link gene function and phenotypic traits, and finally perform functional annotation for each gene. For rice, rice stalks play the role of nutrient transport and lodging resistance, and the rapid and accurate selection of varieties with lodging resistance will be directly related to the improvement of yield and the determination of functional genes. Therefore, the tillering traits of rice Research...
